ZL30155中文资料2-Ch Line Card Synchronizer数据手册Microchip规格书

描述 Description

The ZL30155 Dual Channel Universal Clock Translator, part of Microchip's ClockCenter platform of Synchronous Clock devices, delivers industry leading synchronization performance for high-speed complex applications.  The highly integrated and programmable solution provides translation from any input reference frequency to any output clock frequency with jitter performance that can directly drive 10 G PHY devices.The ZL30155 integrates 2 independent digital PLLs, accepts 4 input references and generates 12 programmable clock outputs.  The highly integrated solution allows designers to replace multiple components with a single chip, simplifying design and reducing component count and power.

特性 Features
